**Pros and Cons of Buying Fuel Injectors (FIC 1220S, DSM 90-99, Impedance 126-1220)**
### **Pros:**1. **Compatibility** These injectors are designed specifically for late-model **Daimler-Chrysler (Dodge, Chrysler, Jeep) vehicles** from the **1990s**, particularly the **DSM platform (e.g., 1990-1999 models)**. They are a direct replacement for the **126-1220** and **1220S** part numbers, ensuring proper fitment without modification.
2. **Impedance Matching** The **126-1220** and **1220S** injectors are **impedance-matched** for the **DSM fuel system**, meaning they work seamlessly with the **ECU (Engine Control Unit)** and **fuel management system** of these vehicles. This reduces the risk of **fuel pressure issues, misfires, or electrical problems** that can occur with mismatched injectors.
3. **High-Quality Build** Fuel Injector Clinic (FIC) is a reputable manufacturer known for producing **durable, high-flow injectors** that meet or exceed OEM specifications. These injectors are built to last longer than many aftermarket alternatives, reducing the likelihood of premature failure.
4. **Better Fuel Efficiency & Performance** Since these injectors are **OEM replacements with improved flow rates**, they can help maintain (or even slightly enhance) **fuel efficiency** and **engine performance** compared to worn or failing original injectors.
5. **Warranty & Support** FIC offers a **warranty** (typically 1-2 years) and customer support, which provides peace of mind in case of defects or installation issues.
6. **Prevents Long-Term Damage** Running with **failing injectors** can lead to **carbon buildup, poor combustion, and damage to catalytic converters or oxygen sensors**. Replacing them early prevents costly repairs down the line.
7. **Easy Installation** Since they are **direct drop-in replacements**, they can be installed by most **mechanics or DIY enthusiasts** with basic fuel system knowledge. No major modifications (like wiring harness changes) are usually required.

### **Cons:**1. **Cost** While not excessively expensive, **OEM-quality injectors** (especially from a trusted brand like FIC) are **more expensive than generic aftermarket alternatives**. Prices typically range from **$100 to $200 per injector**, depending on quantity and discounts.
2. **Potential for Counterfeit or Mismatched Parts** If purchasing from an **unverified seller**, there is a risk of receiving **fake or incorrect part numbers**. Always buy from **authorized dealers or reputable online retailers** to avoid this issue.
3. **Requires Professional Installation (Optional but Recommended)** While possible to install DIY, **fuel injectors are precision components**. If not installed correctly, they can **leak, fail to prime, or cause fuel system issues**. Some buyers opt for **professional installation** to ensure proper sealing and electrical connection.
4. **May Still Require Additional Repairs** If the vehicle has **other fuel system issues** (e.g., **clogged fuel filters, failing fuel pump, or dirty injectors**), simply replacing the injectors may not fully resolve performance problems. A **full fuel system flush or cleaning** may be needed.
5. **Limited Availability of Spare Parts** Since these are **older OEM-style injectors**, finding **replacement seals, O-rings, or wiring harnesses** in case of failure can be **challenging** compared to newer vehicles.
6. **Potential for Overkill on Modernized Engines** If the vehicle has **aftermarket modifications** (e.g., **turbocharging, supercharging, or high-performance tuning**), these **stock-style injectors may not provide enough flow** for optimal performance. In such cases, **high-flow injectors** may be necessary.
7. **Electrical Compatibility Concerns** While impedance-matched, **older vehicles may have wiring issues** (e.g., **corroded connectors, poor grounding**). If the **ECU or fuel pump wiring is damaged**, the injectors may not function properly even if the injectors themselves are fine.

### **Conclusion:**Buying **FIC 1220S/126-1220 injectors for a DSM (90-99) vehicle** is a **strong choice** for those seeking **reliable, OEM-quality replacements** that ensure **proper fuel delivery and engine performance**. The **impedance matching** and **durability** of these injectors make them a **preferred option** over generic aftermarket parts, especially for **restoration or reliability-focused projects**.
However, the **higher cost, potential installation challenges, and need for system-wide checks** (fuel pressure, wiring, filters) mean that buyers should **weigh the long-term benefits against upfront expenses**. If the vehicle has **other fuel system issues**, addressing those first (or simultaneously) will maximize the effectiveness of the injector replacement.
For **most DSM owners looking for a **direct OEM replacement with improved reliability**, these injectors are a **solid investment**. Those on a tight budget may consider **high-quality aftermarket alternatives**, but they risk **compatibility or performance trade-offs**.
### **Recommendation:**- **Buy from an authorized FIC dealer or a trusted online retailer** (e.g., **RockAuto, Summit Racing, or a local auto parts store with a good return policy**) to ensure **genuine, impedance-matched injectors**.
- **Check for accompanying seals, O-rings, and wiring harnesses** if needed.
- **Consider professional installation** if unsure about handling fuel system components.
- **Inspect the rest of the fuel system** (fuel filter, pump, lines, ECU wiring) before and after installation to prevent future issues.
- **Monitor fuel efficiency and engine performance** post-installation if problems persist, consult a **diagnostic scan tool** to rule out ECU or wiring issues.
**Final Verdict:** **Highly recommended for DSM (90-99) owners** needing **reliable, OEM-spec injectors** just ensure proper installation and system compatibility.
The FIC 1220S Fuel Injectors by Fuel Injector Clinic are designed for DSM 90-99 vehicles with low impedance. Replaced all when #4 stopped working. These Injectors are specifically crafted for gasoline Fuel systems, ensuring optimal performance and efficiency. Only 3 are good.
